The above information is presented as background information only to assist with an understanding of the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the present disclosure.

SUMMARY

Aspects of the present disclosure are to address at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the present disclosure is to provide an electronic device and method for controlling a display in an electronic device.

Referring to FIGS. 12A, 12B and 12C, the display of an electronic device may be rectangular in shape. While being placed in parallel with the horizontal surface, the display may be operated in a display status as shown in FIG. 12A, e.g., a vertical mode (also referred to as a ‘portrait mode’) where the horizontal size of the display is smaller than the vertical size of the display or in another display as shown in FIG. 12B, e.g., a horizontal mode (also referred to as a ‘landscape mode’) where the horizontal size of the display is larger than the vertical size of the display. For example, when the electronic device displays, on the display screen, a virtual keypad 1201 for text entry in the horizontal mode as shown in FIG. 12B, the electronic device may enlarge and display the horizontal size of the keypad 1201 that is displayed on the display screen to correspond to the horizontal size of the electronic device.

At least a portion of the kernel 141, middleware 143, or API 145 may be denoted an operating system (OS). For example, the kernel 141 may control or manage system resources (e.g., the bus 110, processor 120, or a memory 130) used to perform operations or functions implemented in other programs (e.g., the middleware 143, API 145, or application program 147). The kernel 141 may provide an interface that allows the middleware 143, the API 145, or the application 147 to access the individual components of the electronic device 101 to control or manage the system resources.

The middleware 143 may function as a relay to allow the API 145 or the application 147 to communicate data with the kernel 141, for example. Further, the middleware 143 may process one or more task requests received from the application program 147 in order of priority. For example, the middleware 143 may assign a priority of using system resources (e.g., bus 110, processor 120, or memory 130) of the electronic device 101 to at least one of the application programs 147 and process one or more task requests. The API 145 is an interface allowing the application 147 to control functions provided from the kernel 141 or the middleware 143. For example, the API 145 may include at least one interface or function (e.g., a command) for filing control, window control, image processing or text control. For example, the input/output interface 150 may transfer commands or data input from the user or other external device to other component(s) of the electronic device 101 or may output commands or data received from other component(s) of the electronic device 101 to the user or other external devices.

The display 160 may include a touchscreen and may receive, e.g., a touch, gesture, proximity or hovering input using an electronic pen or a body portion of the user. For example, the communication interface 170 may set up communication between the electronic device 101 and an external device (e.g., a first electronic device 102, a second electronic device 104, or a server 106). For example, the communication interface 170 may be connected with a network 162 through wireless communication or wired communication and may communicate with an external device (e.g., the second external electronic device 104 or server 106).

The wireless communication may include cellular communication which uses at least one of, e.g., long term evolution (LTE), LTE-advanced (LTE-A), code division multiple access (CDMA), wideband CDMA (WCDMA), universal mobile telecommunication system (UNITS), wireless broadband (WiBro), or global system for mobile communication (GSM). According to an embodiment of the present disclosure, the wireless communication may include at least one of, e.g., wireless fidelity (Wi-Fi), Bluetooth (BT), Bluetooth low power (BLE), zigbee, near field communication (NFC), magnetic secure transmission (MST), radio frequency, or body area network (BAN). According to an embodiment of the present disclosure, the wireless communication may include GNSS. The GNSS may be, e.g., global positioning system (GPS), global navigation satellite system (Glonass), Beidou navigation satellite system (hereinafter, “Beidou”) or Galileo, or the European global satellite-based navigation system. Hereinafter, the terms “GPS” and the “GNSS” may be interchangeably used herein. The wired connection may include at least one of, e.g., universal serial bus (USB), high definition multimedia interface (HDMI), recommended standard (RS)-232, power line communication (PLC), or plain old telephone service (POTS). The network 162 may include at least one of telecommunication networks, e.g., a computer network (e.g., local area network (LAN) or wide area network (WAN)), Internet, or a telephone network.

The first and second external electronic devices 102 and 104 each may be a device of the same or a different type from the electronic device 101. According to an embodiment of the present disclosure, all or some of operations executed on the electronic device 101 may be executed on another or multiple other electronic devices (e.g., the electronic devices 102 and 104 or server 106). According to an embodiment of the present disclosure, when the electronic device 101 should perform some function or service automatically or at a request, the electronic device 101, instead of executing the function or service on its own or additionally, may request another device (e.g., electronic devices 102 and 104 or server 106) to perform at least some functions associated therewith. The other electronic device (e.g., electronic devices 102 and 104 or server 106) may execute the requested functions or additional functions and transfer a result of the execution to the electronic device 101. The electronic device 101 may provide a requested function or service by processing the received result as it is or additionally. To that end, a cloud computing, distributed computing, or client-server computing technique may be used, for example.

For example, the device management application may install, delete, or update a function (e.g., turn-on/turn-off the external electronic device (or some elements) or adjusting the brightness (or resolution) of the display) of the external electronic device communicating with the electronic device or an application operating on the external electronic device. According to an embodiment of the present disclosure, the application 370 may include an application (e.g., a health-care application of a mobile medical device) designated according to an attribute of the external electronic device. According to an embodiment of the present disclosure, the application 370 may include an application received from the external electronic device. At least a portion of the program module 310 may be implemented (e.g., executed) in software, firmware, hardware (e.g., the processor 210), or a combination of at least two or more thereof and may include a module, program, routine, command set, or process for performing one or more functions.

According to an embodiment of the present disclosure, an electronic device (e.g., the electronic device 101) may comprise a touchscreen (e.g., the display 160), at least one processor (e.g., the processor 120) electrically connected with the touchscreen, and a memory (e.g., the memory 130) electrically connected with the processor, wherein the memory may store instructions executed to enable the processor to display a first window for running a first application and a second window for running a second application on the touchscreen, display a virtual keypad on a portion of the first window and a portion of the second window corresponding to a first input to a focused window of the first window and the second window, and vary a size of the virtual keypad corresponding to a second input to the virtual keypad.

For example, the instructions may enable the processor to, when a drag input on a side of the virtual keypad is received, and a length of the drag input is a designated threshold or more, vary the size of the virtual keypad into a designated size according to a direction of the drag input and display the virtual keypad.

For example, a left side of the virtual keypad may be positioned on a left side of the first window, and a right side of the virtual keypad may be positioned on a right side of the second window that is disposed in parallel with the first window.

For example, the instructions may enable the processor to, when a drag input from a left side of the virtual keypad to a right side of the virtual keypad is received, and a length of the drag input is a designated threshold or more, vary the size of the virtual keypad so that the left side of the virtual keypad is positioned on a left side of the second window and display the virtual keypad. The drag input may start at the left side of the virtual keypad.

For example, the instructions may enable the processor to, when a drag input from a right side of the virtual keypad to a left side of the virtual keypad is received, and a length of the drag input is a designated threshold or more, vary the size of the virtual keypad so that the right side of the virtual keypad is positioned on a right side of the first window and display the virtual keypad. The drag input may start at the right side of the virtual keypad.

For example, wherein the instructions may enable the processor to, when a drag input on a side of the virtual keypad is received, vary the size of the virtual keypad in a direction of the drag in proportion to a length of the drag input and display the virtual keypad.

For example, the touchscreen may have a rectangular shape with a horizontal size and a vertical size different from the horizontal size. The electronic device may be operated in a horizontal mode where the first window and the second window are displayed in parallel with each other in a vertical direction of the touchscreen. The first window and the second window may not overlap each other.

For example, the virtual keypad may be positioned in an area of the first window. The instructions may enable the processor to, when a drag input for a boundary between the first window and the second window is received, move the boundary in a direction of the drag input for the boundary in proportion to a length of the drag input for the boundary to adjust a horizontal size of the first window, the second window, and the virtual keypad.

For example, the instructions may enable the processor to display a cursor on a text entry window of an application run on the focused window, and upon receiving a third input for a text entry window of the first window or the second window which is not the focused window, terminate the display of the cursor and display the cursor on a text entry window where the third input is sensed.

For example, the instructions may enable the processor to display the virtual keypad on a portion of the first window upon receiving a touch input to a text entry window of the first application of the first window while the virtual keypad is displayed on a portion of the second window.

For example, the touchscreen may be a single screen.

FIG. 4 is a flowchart illustrating operations for controlling a display screen of an electronic device according to an embodiment of the present disclosure.

In operation 410, the electronic device may display a multi-window screen. For example, the multi-window screen may include a first window for running a first application and a second window for running a second application. The first window and the second window may partially overlap or may be separately displayed.

In operation 430, the electronic device may display a virtual keypad for an application run on the window that is focused on the multi-window screen. For example, the electronic device may focus the first window or the second window according to a user input (e.g., a touch). The electronic device may display a virtual keypad for the first application run on the first window or the second application run on the second window according to a user input. The virtual keypad may be displayed on a portion of the first window or a portion of the second window. The horizontal size of the virtual keypad may be the same (or correspond to the horizontal size of the display of the electronic device) as the sum of the horizontal size of the first window and the horizontal size of the second window.

In operation 450, the electronic device may adjust the size of the virtual keypad according to a user input. For example, the electronic device may adjust the size of the virtual keypad according to a drag input on a portion of the virtual keypad. The electronic device may adjust the size of the virtual keypad according to the length of the drag input and the direction of the drag input. The portion of the virtual keypad may be an upper, lower, left, or right side (also referred to as an edge) portion of the virtual keypad.

FIG. 5 is a flowchart illustrating operations for adjusting the size of a virtual keypad of an electronic device according to an embodiment of the present disclosure. FIGS. 6A to 6D are views illustrating operations for adjusting the size of a virtual keypad of an electronic device according to various embodiments of the present disclosure.

Referring to FIG. 5 and FIGS. 6A to 6D, the electronic device may adjust the size of the virtual keypad to correspond to the size of one of the windows included in the multi-window screen according to a user input.

In operation 510, the electronic device may display a multi-window screen.

Referring to FIG. 6A, the electronic device may be operated in a display status as shown in FIG. 6A, e.g., a horizontal mode (also referred to as a ‘landscape mode’) where the horizontal size is larger than the vertical size. The electronic device, when being operated in a multi-window and horizontal mode, may split the display screen into two areas and may display a first window 601 on a left-hand display screen and a second window 602 on a right-hand display screen as shown in FIG. 6A. The first window 601 may display an execution screen of a first application, and the second window 602 may display an execution screen of a second application.

In operation 520, the electronic device may display a virtual keypad for an application run on the window that is focused on the multi-window screen.

Upon receiving a user input for running a virtual keypad for the second application run on the second window 602 while displaying the first window 601 and the second window 602 in the horizontal mode as shown in FIG. 6A, the electronic device may display a virtual keypad 603 on a portion of the first window 601 and a portion of the second window 602 as shown in FIG. 6B. For example, upon sensing a touch on a text entry window 604 of the execution screen of the second application, the electronic device may display the virtual keypad 603 on the lower portion of the first window 601 and the second window 602 as shown in FIG. 6B. For example, the electronic device may reduce the vertical size of the display screen of the second application, generate an area, where a portion of the virtual keypad 603 may be positioned, in the lower portion of the second window 602, and display the virtual keypad 603 on the area generated in the lower portion of the second window 602 and a lower portion of the first window 601. As another example, the electronic device may reduce both the vertical size of the display screen of the first application and the vertical size of the display screen of the second application, generate an area, where the virtual keypad 603 may be positioned, and display the virtual keypad 603 on the area generated in the lower portion of the first window 601 and the area generated in the lower portion of the second window 602.

In operation 530, the electronic device may sense a drag input on a side of the virtual keypad. For example, when the user drags a left-hand side 605 of the virtual keypad 603 to the right where the second window 602 is positioned as shown in FIG. 6B, the electronic device may sense the drag input.

In operation 540, the electronic device may determine whether the length of the drag input (which is also referred to as the distance of drag input) is larger than a predetermined threshold.

For example, the length of the drag input may be a distance at which the user's finger or a touch tool moves from where the touch is made by the finger or touch tool to where the touch is released in the display. Or, the length of the drag input may be a distance at which the user's finger or a touch tool moves from where a hovering of the finger or touch tool is recognized to where the recognition of the hovering is ended in the display.

For example, the threshold may be proportionate to the horizontal size (or keypad width) 606 of the virtual keypad 603 as shown in FIG. 6C. The threshold may be determined by Equation 1 below. Threshold=horizontal size 606 of virtual keypad/n(n>=2, n is a positive integer)   Equation 1

The electronic device may perform operation 550 when determining in operation 540 that the length of the drag input is larger than the predetermined threshold and may otherwise perform operation 530 again.

In operation 550, the electronic device may update the horizontal size of the virtual keypad. For example, the updated horizontal size of the virtual keypad may be the same as the horizontal size of a focused window.

In operation 560, the electronic device may vary the position of the virtual keypad to a lower portion of the focused window.

When the user drags the left-hand side 605 of the virtual keypad 603 to the right where the second window 602 is positioned as shown in FIG. 6B, if the length of the drag input is larger than the threshold, the electronic device may be positioned in the direction of the drag as shown in FIG. 6D, reduce the horizontal size of the virtual keypad 603 to the same size as the horizontal size 606 of the second window 602 focused, and position the virtual keypad 603 on a lower portion of the second window 602.

According to an embodiment of the present disclosure, a method for controlling a display in an electronic device may comprise displaying a first window for running a first application and a second window for running a second application on a touchscreen of the electronic device, displaying a virtual keypad on a portion of the first window and a portion of the second window corresponding to a first input to a focused window of the first window and the second window, and varying a size of the virtual keypad corresponding to a second input to the virtual keypad.

For example, varying the size of the virtual keypad may include, when a drag input on a side of the virtual keypad is received, and a length of the drag input is a designated threshold or more, varying the size of the virtual keypad into a designated size according to a direction of the drag input and displaying the virtual keypad.

For example, a left side of the virtual keypad may be positioned on a left side of the first window, and a right side of the virtual keypad may be positioned on a right side of the second window that is disposed in parallel with the first window.

For example, varying the size of the virtual keypad may include, when a drag input from a left side of the virtual keypad to a right side of the virtual keypad is received, and a length of the drag input is a designated threshold or more, varying the size of the virtual keypad so that the left side of the virtual keypad is positioned on a left side of the second window and displaying the virtual keypad, and when a drag input from a right side of the virtual keypad to a left side of the virtual keypad is received, and a length of the drag input is a designated threshold or more, varying the size of the virtual keypad so that the right side of the virtual keypad is positioned on a right side of the first window and displaying the virtual keypad.

For example, varying the size of the virtual keypad may include, when a drag input on a side of the virtual keypad is received, varying the size of the virtual keypad in a direction of the drag in proportion to a length of the drag input and displaying the virtual keypad.

For example, the touchscreen may have a rectangular shape with a horizontal size and a vertical size different from the horizontal size. The electronic device may be operated in a horizontal mode where the first window and the second window are displayed in parallel with each other in a vertical direction of the touchscreen. The first window and the second window may not overlap each other.

For example, the virtual keypad may be positioned on any one portion of the first window.
